Sony isn't publishing Resident Evil: Revelations 2. Capcom is. It's a multi-platform title, and it takes little effort to crank out a PS Vita version using Sony's tools once the PS3/PS4 version is done. It's digital only outside of Japan, as well.

Well Capcom may have published it but Sony had to port it themselves. They even got a small team of indie programmers to help out in the long run. End result it's pretty smooth and I'm grateful for this even despite download only....Thanks Sony.
